I want to know the details of touching and going. How long do I have to touch before I can go, and have another landing? Can I perform multiple touch and goes on the same runway? How many? Does the hardness of the touch effect XP? Do I have to land with a certain hardness for it to count as a touch and go?
30 seconds between each touch and go
Short answer, yes but that time difference is important.
As many as you would like
Difficulty of the landing does affect xp. For example, more winds = more xp
Nope, but I would recommend touching down fully before rotating again
If you are doing a proper touch and go, you want to straighten out, and then go TOGA.
Landing VS and winds both affect XP I think.
